3200mhz Memory Overclock

[Joxeon]

No worries.

Memory o/c been running fine for several days - passes memtest fine
Just checked benchmarks in AIDA64 and get these results:
Read - 56455 MB/s
Write - 30389MB/s
Copy - 53263 MB/s
Latency - 67.6ns

The 'write' looks very low - or is this ok?

CL 16
RCD 16
RP 16
RAS 32

The write is normal for 3000 CPUs with 8 core or less.

Ok thanks - was worried that I had tightened things a little too far somewhere

With a bit more tweaking, got the latency down to 64.7

Can you explain how you have 3800 running without being halved? I thought the max was 3733 for 1:1 if your silicon was good?

Are you using all the values provided by Ryzen DRAM Calculator?
Tried here, was fine for gaming, normal use, but crashed during memtest.

I started with the values from the DRAM Calc - but fast settings at first were not stable and gave me errors (I did have a major issue at first, causing me to re-install W10 as could not recover no matter what I tried (wasted a full day on it as well)).
A weekend of tweaking and retrying solved it for me = now stable and passing all tests.

3800 is fine if you have a chip that will do 1900 fclk.
